Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0047] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0048] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0049] This utility model proposes an embodiment of a grinding pillow component, which is mainly used to adapt to the structure of a grinding machine in which the grinding pillow component drives the sanding belt to move for grinding. When the grinding pillow component drives the sanding belt to move for grinding, it is necessary to ensure that the grinding pillow component and the sanding belt are tightly connected and do not have relative displacement. If the two are relatively displaced, normal grinding cannot be performed.

[0050] Specifically, the grinding pillow component includes:

[0051] The grinding pillow base is 100mm long and narrow.

[0052] When setting up, the grinding and vibration base can be configured as a long rectangular parallelepiped structure with its bottom surface set as a plane.

[0053] The entire grinding pad base 100 is designed as a long strip structure, with a length of 1000-1060cm and a width of 170-190cm. The large area increases the contact area between the grinding pad and the sanding belt, thereby increasing the contact area between the sanding belt and the board, enabling large-area rapid grinding and improving grinding efficiency.

[0054] The grinding pillow base 100 is a rigid component. During molding, the grinding pillow base 100 can be made of aluminum profile to reduce the weight of the entire grinding pillow base 100.

[0055] The grinding pillow component includes an elastic buffer 200, which is arranged below the grinding pillow base 100 and extends along the length of the grinding pillow base 100.

[0056] When in use, the grinding pillow component mainly drives the sanding belt to move and grind the plate through sanding belts of different fineness.

[0057] Since the grinding pillow base 100 is a rigid component, if it directly drives the abrasive belt to wear the plate, the grinding pillow base 100 and the plate will have a rigid contact fit, which may damage the plate being ground.

[0058] To avoid the above problems, an elastic buffer 200 is arranged below the grinding pad base 100. The elastic buffer 200 is elastic and can play a certain buffering role. This can avoid the hard contact between the grinding pad base 100 and the plate, and effectively avoid the problem of damage to the plate when grinding.

[0059] The elastic buffer 200 can change with the shape of the sanding belt, maintaining close contact with it at all times. This effectively increases the support for the sanding belt, allowing it to better conform to the surface of the material being sanded. It can also adapt its shape to the surface shape of the material being sanded, improving the sanding effect and enhancing its performance.

[0060] Wear-resistant component 300 is arranged along the length of the grinding pillow base 100 and below the elastic buffer component 200. After wrapping the elastic buffer component 200, its two ends are bent upward and fixedly connected to the grinding pillow base 100.

[0061] The wear-resistant part 300 is made of graphite cloth, which is used to reduce wear between the wear-resistant part and the abrasive belt.

[0062] When the graphite cloth is installed, it is attached to the bottom position of the elastic buffer 200, and its two ends along the width direction extend upward along the two sides of the elastic buffer 200 to the two sides of the grinding pillow base 100 and connect with the grinding pillow base 100.

[0063] The elastic buffer 200 can be wrapped and pressed between the graphite cloth and the grinding pillow base 100 to fix the elastic buffer 200.

[0064] An adsorption channel is formed between the wear-resistant part 300, the elastic buffer part 200 and the grinding pillow substrate 100.

[0065] In this embodiment, the grinding pillow component can be used in conjunction with a negative pressure fan. By arranging the negative pressure fan and the adsorption channel in a corresponding manner, a negative pressure is generated inside the adsorption channel when the adsorption fan is working. Through the negative pressure, the abrasive belt wrapped around the grinding pillow base 100 is firmly adsorbed onto the grinding pillow base 100, making it adaptable to the grinding machine structure in which the grinding pillow component drives the abrasive belt to move and grind. Moreover, during the grinding process, the negative pressure adsorption prevents the abrasive belt from moving and changing position relative to the grinding pillow component, thus ensuring the grinding effect.

[0066] In some embodiments of this application, the grinding pillow component includes:

[0067] Two clamping parts 410 are provided, which are used to clamp the two ends of the wear-resistant part 300 respectively;

[0068] The locking member 420 passes through the pressing member 410 and is locked and fixed inside the grinding pillow base 100.

[0069] The pressing component 410 is a pressing plate that extends along the length of the wear-resistant substrate to uniformly press and fix the end of the wear-resistant component 300, thereby ensuring the grinding effect.

[0070] The locking element 420 is a locking screw, which passes through the pressing element 410 and is locked and fixed in the wear-resistant substrate to fix the pressing element 410.

[0071] In some embodiments of this application, the grinding wheel substrate 100 includes:

[0072] Two first grinding wheel bases 110 are provided, arranged symmetrically.

[0073] The second grinding wheel base 120 is located below the first grinding wheel base 110, and its two ends are respectively connected and fixed to the two first grinding wheel bases 110;

[0074] Reinforcing connectors 130 are connected between two first grinding pad bases 110, and multiple such connectors are provided and arranged along the length of the first grinding pad bases 110.

[0075] The first grinding pillow base 110 is the first grinding pillow beam, and two of them are set up symmetrically, with a gap between the two first grinding pillow beams.

[0076] The second grinding pillow base 120 is a second grinding pillow plate, which is rectangular and is attached to the bottom surface of the two first grinding pillow bases 110 and locked and fixed to the two first grinding pillow bases 110.

[0077] The reinforcing connector 130 is a reinforcing connecting plate, which is arranged above the second grinding pad plate, perpendicular to the two first grinding pad bases 110 and connected to the two first grinding pad bases 110 at both ends, so as to enhance the strength of the entire grinding pad base 100.

[0078] In some embodiments of this application, the first grinding wheel substrate 110 includes:

[0079] The first connecting part 111 corresponds to the position of the second grinding wheel base 120 and is used to connect and fix the second grinding wheel base 120.

[0080] The second connecting part 112 is disposed on the side of the first grinding pillow base 110 and is used to connect and fix it with the pressing member 410.

[0081] The third connecting portion 113 is arranged opposite to the first connecting portion 111;

[0082] The fourth connecting part 114 is used to connect and fix with the reinforcing connecting member 130.

[0083] The first connecting part 111 is a first connecting slot with an opening formed on the first grinding wheel base 110. A first square nut is provided and locked in the first connecting slot. When it is connected to the second grinding wheel base 120, the first locking screw passes through the second grinding wheel base 120 and is inserted into the first connecting slot and locked and fixed with the first square nut.

[0084] The second connecting part 112 is a second connecting groove formed on the side of the first grinding wheel base 110, and a second square nut is engaged in the second connecting groove.

[0085] When the second connecting part 112 is connected to the pressing member 410, the second locking screw passes through the pressing member 410 and is screwed into the second square nut in the second connecting groove.

[0086] The third connecting part 113 is the third connecting slot.

[0087] The fourth connecting part 114 is a fourth connecting slot, and a fourth square nut is installed in the fourth connecting slot. During connection, the fourth locking screw passes through the reinforcing connector 130 and is screwed into the fourth square nut in the fourth connecting slot for fixation.

[0088] In some embodiments of this application, a first flow hole 121 is formed on the grinding wheel substrate 100;

[0089] A second flow hole is formed on the elastic buffer member 200;

[0090] A third flow hole is formed on the wear-resistant part 300;

[0091] The first flow hole 121, the second flow hole and the third flow hole are interconnected to form the adsorption channel.

[0092] In a specific configuration, the first flow hole 121 is set on the second grinding pillow base 120, and multiple rows are set, with each row arranged along the length direction of the grinding pillow base 100.

[0093] The second flow holes are also arranged in multiple rows, each corresponding to a different position on the second grinding wheel base 120, to ensure mutual communication.

[0094] The wear-resistant part 300 is made of graphite cloth, and the gaps between the holes formed by its weaving constitute the third flow hole.

[0095] When a negative pressure is generated in the adsorption channel, the sand belt wrapped around the grinding pillow component will be firmly adsorbed.

[0096] In some embodiments of this application, the elastic buffer 200 is made of rubber, foam, sponge or soft rubber, but is not limited to the above materials, as long as it can play an elastic buffering role.

[0097] In some embodiments of this application, the width of the elastic buffer 200 is smaller than the width of the second grinding pillow base 120.

[0098] In some embodiments of this application, a feed side 510 and a discharge side 520 are formed on at least two sides of the second grinding pillow base 120 and the elastic buffer member 200, respectively, and a guide portion is formed at the feed side 510 and / or the discharge side 520.

[0099] By setting up the guide section, when it is necessary to change the position of the sanding belt, the force applied to the sanding belt will be used to move it along the grinding bolster component, so as to smoothly guide the sanding belt and avoid the sanding belt breaking or being damaged when it is in right-angle contact with the grinding bolster component.

[0100] A feed side 510 and a discharge side 520 are formed on one side of the grinding pillow base 100 and the elastic buffer member 200, respectively. Both the feed side 510 and the discharge side 520 are in contact with the sanding belt. When the sanding belt is installed, a guide part is provided at least at the feed side 510 position of the second grinding pillow base 120 and the elastic buffer member 200 to smoothly guide the sanding belt.

[0101] In some embodiments, the guide portion is provided on both sides of the feed side 510 and the discharge side 520 of the grinding pillow base 100. When the sanding belt is moved to a different position, the unused sanding belt segment can be smoothly guided to the bottom of the grinding pillow component, and the used sanding belt segment can be smoothly discharged to avoid damage to the sanding belt.

[0102] In some embodiments of this application, the guide portion includes a first guide surface 122 formed on the second grinding wheel base 120 and a second guide surface 220 formed on the elastic buffer 200.

[0103] The first guide surface 122 is a first guide slope, and the second guide surface 220 is a second guide slope. The first guide slope and the second guide slope have the same inclination direction and inclination angle.

[0104] The bottom surface of the elastic buffer 200 is a plane, and the first guide slope and the second guide slope can be mated together to achieve the tilting and guiding effect on the sand belt.

[0106] By setting the first guide surface 122 as a first guide arc surface and the second guide surface 220 as a second guide arc surface in a mating manner, smooth guidance can also be achieved during the movement of the sand belt.
